Orłowski M, Tarczydło B, Chałas R - ScientificWorldJournal (2015)

Bottom Line: The prepared tooth samples were placed in a 1% methylene blue solution for 24 h, and after that in each restoration the depth of dye penetration along the side walls was evaluated.The highest rating (score 0, no dye penetration) was achieved by 93.33% of the restorations made of the SDR material, 90% of restorations of SonicFill system, 86.66% of restorations of the composite Filtek Bulk Fill, and 73.33% of restorations of the Tetric EvoCeram Bulk Fill.The performed study showed that bulk-fill flowable or sonic-activated flowable composite restorations have better marginal sealing (lack of discoloration) in comparison with bulk-fill paste-like composite.

ABSTRACT

Objective: The aim of the study was to compare under in vitro conditions marginal sealing of 4 different bulk-fill materials composite restorations of class II.

Methods: Comparative evaluation concerned 4 composites of a bulk-fill type: SonicFill, Tetric EvoCeram Bulk Fill, Filtek Bulk Fill, and SDR. The study used 30 third molars without caries. In each tooth 4 cavities of class II were prepared. The prepared tooth samples were placed in a 1% methylene blue solution for 24 h, and after that in each restoration the depth of dye penetration along the side walls was evaluated.

Results: The highest rating (score 0, no dye penetration) was achieved by 93.33% of the restorations made of the SDR material, 90% of restorations of SonicFill system, 86.66% of restorations of the composite Filtek Bulk Fill, and 73.33% of restorations of the Tetric EvoCeram Bulk Fill.

Conclusion: The performed study showed that bulk-fill flowable or sonic-activated flowable composite restorations have better marginal sealing (lack of discoloration) in comparison with bulk-fill paste-like composite.

Mentions: Dye penetration rating using the grade scale was as follows (Table 2): the highest rating (score 0, no dye penetration) was achieved by 93.33% of the restorations made of the SDR material; 90% of restorations of SonicFill system; 86.66% of restorations of the composite Filtek Bulk Fill; and 73.33% of restorations of the Tetric EvoCeram Bulk Fill. The chosen tooth's sample without discoloration is presented in Figure 3. Score 1 (penetration of dye into half-depth of one wall) was achieved by 23.33% of restorations made of composite Tetric EvoCeram Bulk Fill and 3.33% of restorations from all other tested materials. Dye penetration along the entire length of one wall (score 2) was not found in the fillings made of the materials SonicFill and Tetric EvoCeram Bulk Fill and was observed in 6.66% of restorations made of Filtek Bulk Fill and 3.33% of the restorations made of SDR. The penetration of dye into half-depth of the two walls (score 3) of studied restorations was found only in the case of 6.66% of restorations of SonicFill and 3.33% of Filtek Bulk Fill restorations. Score 4 was achieved only by 3.33% restorations of the composite Tetric EvoCeram Bulk Fill. The chosen tooth's sample is presented in Figure 4. In these fillings, complete discoloration was seen on both walls. In the remaining materials tested, there was no discoloration of the two walls. All rates are graphically presented in Figure 5.
